Figure; 3 is a rear elevation, with the beam-plate ne shown.

Similar letters ef reference indicate cerresponding parts in all the figures. v

Tire nature of this invention relates to improvemonts in tire jointe! coupling for attaehing tire beams et cultivators t0 tlne main fraine; and

Tire invention consists in a simple arrangement ef bearingplates and an eye-b0lt, se constructed and arranged, in combination with the beam-plate and journal-spindle, as te admit et the most pertect lateral and vertical adjustment, and lateral and vertical movcment or oscillation. V

Te enable others to nnderstand the construction and opemtien of my invention, I will proceed to describe it with reference to the dra'wings.

A represents the jonrnal-spixnlle et tire main framc, te whieh the beams of the plows arc usually attached by means of a joint.

B rcprescnts grooves around the spindle A, of which there may be any desiled nnmhor.

This plate E hasalxol through the centre, through which passes tire shank of the eye-bolt O.

H represent's acylindrical projection on the face ef the plate E, and forms the bearingsnrface.fer the beam-plate J, taking the strain et the draught ei' et tire boit C, by means et the flanges (I, and allewing froc verticalmevement of the plews.

K reprcSents anether plate, with a projection or grooves B, by sliding the whole -device on the spin' dle A.

Lziteral movement may be obtained by the eye-bolt slidingen and around the spindle A.

Tire foregoing description relates to the spindle A as used in a vertical position. It may, however, be

used in a horizontal position.

WVhat I-cIaim as my invention, and desire to secure by Letters Patent, is-

Tire combinatien and arrangement ef the plates E and K, with their respective projections H and 8, and tongne 0, with the eye-bolt C, nnt D, greoved journalspindle A, and beam-plate J, snbstantidly as described, and for tire purpese set fortin.
